The fun just keeps on going on over at jeep.geocaching.com, as they've announced the August and September winners of their "Jeep 4x4 Geocaching Challenge".

The photos seem to get more and more inventive each month - but we think there might be some Photoshopping going on...

In case you missed it, the contest involves geocaching (a sport where you use a GPS device to find hidden caches), special Jeep travel bugs (Jeep-branded dog tags with a red Commander toy attached), and a photography. If you find a Jeep travel bug, then you can take a photo of it, then submit it to the contest site. Each month, they'll select the best photo and that person will win a Garmin GPS unit. At the end of the contest, they'll select one winner of an all-new 2008 Jeep Liberty.
